Details

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:128.0) Gecko/20100101 Firefox/128.0

Steps to reproduce:

  1. Launch Firefox
  2. Go to "About:config"
  3. Search for extensions.quarantinedDomains.list
  4. Change extensions.quarantinedDomains.list value to null or try adding a custom value
  5. Restart Firefox

Actual results:

When Firefox restarts, extensions.quarantinedDomains.list displays default values instead of custom values.

Expected results:

User input in extensions.quarantinedDomains.list should have been preserved.

Changing the values for extensions.quarantinedDomains.list allows a user to protect certain sensitive domains (ex. www.lastpass.com) from extensions which are designed to scan webpages including ad blockers (ex. uBlock Origin) and citation aid tools (ex. Zotero Connector). While these extensions are benign, the user may wish to take these steps to isolate sensitive data as a contingency plan in case such extensions become compromised.

The Bugbug bot thinks this bug should belong to the 'WebExtensions::Untriaged' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Product: Firefox → WebExtensions

This is working as intended - the pref is not supposed to be modified directly.

The feature that you're describing sounds similar to bug 1745823.
